"Gordon Ramsay, who has seen the videos, says the young actor's likeness is so good, his son believes it is actually him.

The celebrity chef said: 'I was with my son Jack and wife Tana when I received a link to the video. I said, "Look, come and see daddy when he was eight".

'Jack watched it and got upset because he thought I was talking to his grandma like that. For the last 24 hours I've been trying to tell him that it's not me, but he's absolutely convinced that it is.'"
